Has the nighttime fussing been since she's been in this routine hun? The only reason I ask is that's a very short first A in comparison with the last one. I'd expect a minimum of 3hrs A first thing for an 8mo. I'm surprised you're not getting EW!
If the routine has been the same for a while and this has only been happening for a week or two like you said, I would check for teeth? DD was awful at nighttime wrt to teething whereas during the day it didn't affect her much.
You've got room to stretch your day a little hun, you're expecting a lot of sleep overall there. Would you consider moving the first A out by 15mins for now? I think another push would be in order to get you to at least a 12hr day and night with those naps. I wouldn't extend the last a as it's rather long now as it is xx
